我国北方镉污染农田适宜镉低积累小麦品种筛选及各部位镉积累特征分析
Screening of suitable wheat varieties with low cadmium accumulation in cadmium-contaminated farmland in northern China and characterization of cadmium accumulation
摘要
Abstract
In order to screen out wheat varieties with low cadmium(Cd)accumulation that are suitable for planting in Cd-polluted farmland in northern China,the present study utilized 299 wheat materials with rich genetic backgrounds and planted them in Cd-polluted farmland in Tongguan,Shaanxi Province,and Jiyuan,Henan Province,to conduct a two-year screening test of low Cd accumulation varieties of wheat.The results showed that there were significant differences in the Cd content between different wheat varieties,and the ranges of Cd content of grain between different wheat varieties in Tongguan and Jiyuan were 0.073-0.247 and 0.003-0.491 mg kg-1,respectively,and the difference in the Cd content of grain between different wheat varieties could be up to 3.38 and 163.67 times.Using cluster analysis method combined with national safety standard for Cd content of wheat grain in China(＜0.1 mg·kg-1),10 wheat germplasm with low Cd accumulation were preliminarily screened out:Sylvie,Nadosinska,SOUS-1/ARREHANE,China Spring,Mingxian 169,Shuiyuan 11,Luomai 23,Jimai 22,Hongzhongermai,and Liangchun 1571.Combined with the agronomic traits of wheat,three varieties with better yield traits and low Cd accumulation characteristic were finally identified:Luomai 23,Jimai 22,and Liangchun 1571.At the same time,we selected 8 wheat varieties with significant differences in Cd accumulation characteristic of grain to analyze the differences in Cd accumulation characteristic in each wheat part,and identified the key parts that affect the accumulation of Cd in wheat grain:root,flag leaf,sub-spike node,sub-spike node,spike rachi.In summary,in this study,we not only screened out low Cd accumulation wheat varieties suitable for planting in Cd-contaminated farmland in northern China,enriched low Cd accumulation wheat germplasm resources,and at the same time determined the key parts of wheat grain affecting Cd accumulation,so as to provide theoretical guidance for the safe planting of wheat in Cd-contaminated farmland in northern China.关键词
